Hey guys lets see if anyone can help me here :
I have a MOOG BLDC motor and after several weeks of research I'm starting my design :
Vm=330, Max RPM 6000, IC = 6A ..
Now the main problem I have is that the MOOG motor is very old! it has a resolver mounted on it. I'm am trying to figure out how i can determine the rotor position ? Most techniques for commutation control involve using embedded hall effect sensors..
Are there any experiments people know off on how i can determine this rotor position ? given that there is no room on the shaft after i attach the gear to mount a position encoder.
does anyone know how i can use the resolver, i have the data sheet and location of the s1 s2 ect... but i am worried. What if the resolver was not aligned at zero.. it is an old motor.. what if the MOOG control system accounted for this missalignment?
I am building a electric go-kart, capable of reaching approx 60km, all my prelim cals say this motor can do it, its just a matter of controlling it. I want max torque so i want to allign the rotor flux and stator current at 90degs.
But how i use the resolver data.. if i can.. baffels me.
given that i dont need micron accuracy as in a CNC machince for example are there any other techniques I could use to control the commutation of this motor ??
Cheers
